Description

Technical Field

[0001] This utility model relates to the field of damper support technology, and in particular to a viscous damper support structure for vibration reduction in public buildings. Background Technology

[0002] In the field of seismic design for public buildings, energy dissipation and damping technology, which dissipates seismic energy through additional damping devices, is a core means of improving structural safety. Currently, most mainstream solutions use single-mechanism dampers. For example, traditional viscous dampers rely on liquid media to dissipate energy, but they have drawbacks such as leakage due to sealing failure and insufficient damping force under low-frequency conditions. Friction dampers can dissipate energy through sliding friction, but they face problems such as unstable friction coefficients and the need for regular maintenance. Spring dampers can provide elastic buffering, but they are prone to structural resonance when used alone and cannot effectively dissipate energy.

[0003] To address the aforementioned technical bottlenecks, this invention proposes a multi-mechanism synergistic viscous damper support structure. Its innovations lie in: first, resolving the leakage risks of traditional liquid dampers by utilizing the opposing sliding energy dissipation of sliders within the sliding frame; second, employing a lever structure formed by a top / bottom shaft hinged rotating plate to drive the unloading block to slide within the extension frame, generating frictional energy dissipation and compensating for the performance limitations of a single viscous damper under moderate earthquake conditions; and third, combining it with an elastic buffer system of telescopic column sleeve springs to achieve energy absorption during minor earthquakes and post-earthquake recovery. This layered synergistic mechanism (viscous energy dissipation dominating high-frequency large earthquakes, mechanical friction enhancing moderate earthquake response, and elastic buffering adapting to low-frequency small earthquakes) effectively improves vibration reduction efficiency, reduces the amount of dampers used, minimizes building space occupation, and significantly enhances the durability and ease of maintenance of the device. Therefore, this invention proposes a viscous damper support structure for vibration reduction in public buildings to solve the aforementioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 4 This utility model provides an embodiment of a viscous damper support structure for vibration reduction in public buildings, including a sliding frame 1, which serves as the core constraint frame. A slider 2 is slidably connected inside the sliding frame 1, converting the relative displacement caused by building vibrations into its own sliding displacement within the sliding frame 1. A slider 3 is also slidably connected inside the sliding frame 1, converting the relative displacement caused by building vibrations into its own sliding displacement within the sliding frame 1. One end of slider 2 is fixedly connected to a top plate 4, which supports the vibrations of the building structure. One end of slider 3 is fixedly connected to a bottom plate 5. The base plate 5 is designed to provide reaction support as an anchoring foundation. Multiple top shafts 6 are fixedly connected to the outside of the top plate 4. The top shafts 6 are designed to change the magnitude and direction of the force through the lever principle. Multiple bottom shafts 7 are fixedly connected to the outside of the base plate 5. The bottom shafts 7 are designed to change the magnitude and direction of the force through the lever principle. Rotating plates 8 are rotatably connected to the outside of the multiple top shafts 6. Rotating plates 8 are designed to amplify / reduce displacement by utilizing the difference in lever arm. Rotating plates 9 are rotatably connected to the outside of the multiple bottom shafts 7. Rotating plates 9 are designed to amplify / reduce displacement by utilizing the difference in lever arm. Rotating plates 8 are rotatably connected to the outside of rotating plates 9.

[0031] Both sides of the sliding frame 1 are fixedly connected to extension frames 10. The extension frames 10 are designed to limit movement along the extension direction. The external of the extension frames 10 is slidably connected to a stress relief block 11. The stress relief block 11 is designed to convert mechanical kinetic energy into heat energy by frictional resistance between itself and the frame when sliding inside the extension frames 10, directly consuming vibration energy. At the same time, its sliding process extends the force transmission path, further buffering instantaneous impact. One end of the rotating plate 8 is rotatably connected to the outside of the stress relief block 11. Multiple telescopic columns 12 are fixedly connected to the outside of the sliding frame 1. The telescopic columns 12 are designed to act as rigid constraints and directional force transmission. Springs 13 are sleeved on the outside of the telescopic columns 12. The springs 13 are designed to act as elastic energy storage and graded buffering. One end of the multiple telescopic columns 12 is fixedly connected to the inside of the top plate 4. One end of the multiple telescopic columns 12 is fixedly connected to the inside of the bottom plate 5. One end of the multiple springs 13 is fixedly connected to the inside of the top plate 4. One end of the multiple springs 13 is fixedly connected to the inside of the bottom plate 5.

[0032] Working Principle: The viscous damper support structure for this public building achieves vibration reduction through a synergistic mechanism of mechanical transmission unloading, elastic buffering, and viscous energy dissipation. In this structure, the top plate 4 connects to the main building body, the bottom plate 5 is anchored to the foundation, and sliders 2 and 3 are slidably installed within the sliding frame 1. The top plate 4 and bottom plate 5 are also hinged to a rotating plate 8 / rotating plate 9 via a top shaft 6 and a bottom shaft 7, forming a lever structure. Unloading blocks 11 are installed within the extension frames 10 on both sides of the sliding frame 1, and external telescopic columns 12 are fitted with springs 13. When dynamic loads such as earthquakes are applied, the relative displacement of the top plate 4 and bottom plate 5 triggers multi-path energy dissipation. In terms of mechanical unloading, the top shaft 6 and bottom shaft 7 drive the rotating plates to form a "scissor brace" lever to disperse the peak load, simultaneously pushing the unloading blocks 11 to slide within the extension frames 10 to dissipate instantaneous impact energy through friction. In terms of elastic buffering, the telescopic column 12 provides rigid support, while the spring 13 absorbs low-frequency, small-amplitude energy from minor earthquakes and wind-induced vibrations through elastic deformation and assists in post-earthquake recovery with elastic restoring force. In terms of viscous energy dissipation, multiple sliders slide within the sliding frame 1, generating viscous resistance related to displacement velocity (the faster the displacement, the stronger the resistance), efficiently dissipating high-frequency vibration energy during major earthquakes. The three elements work in layers and in synergy: during minor earthquakes, the elastic deformation of the spring 13 and viscous resistance dominate energy absorption; during moderate earthquakes, the mechanical lever unloading and viscous energy dissipation have a superimposed effect; and under major earthquake conditions, the entire system responds in a coordinated manner. This maximizes load unloading through the lever effect and uses the extreme deformation of the spring 13 for buffering and high-speed viscous resistance for strong energy dissipation, ultimately effectively suppressing structural resonance, reducing load transmission amplitude and residual deformation, and improving the seismic safety and durability of public buildings.
